Outlook AddIn Pane detaches from within Outlook reading pane

Modified on: Tue, 16 Oct, 2018 at 10:16 AM

The patch update to Office 2016 / 365 which started distributing in early September 2018 has a flaw. As a result the Outlook AddIn pane can become detached from the reading pane in Outlook, appearing as a separate window on the desktop with a title 'AdxTaskPane'. This issue affects many AddIns, not just that from Legrand CRM, but impacts only Office 2016 / 365 - earlier releases of Microsoft Office are unaffected. It has been acknowledged as a fault by Microsoft and will (presumably) be corrected in a subsequent patch release.

In the meantime the following workaround will prevent this behaviour from occurring:

Open the Outlook Application and navigate to File > Options > General > User Interface options
